摘要： A device for mounting a line pipe in a rotor shaft of a wind turbine. The invention also relates to a rotor shaft for a wind turbine and to the wind turbine itself. The device includes a rotor shaft which is configured to be partially hollow and in which the line pipe is arranged. In the line pipe, different media are routed from a fixed nacelle of the wind turbine in the direction of a rotor hub connected to the rotor shaft. These can be not only electrical lines but also optical waveguides and media lines for gases and liquids. The mounting of the line pipe is achieved by a device having a plurality of eccentric fixing elements, wherein the line pipe is oriented concentrically by rotating the eccentric fixing elements.

摘要： A method for controlling an active power in a wind farm comprises inputting an active power setpoint value into the wind farm model. Splitting the active power setpoint value of the wind farm among models of the wind turbines. Determining a modeled active power setpoint value of the wind farm as a sum of modeled active power setpoint values of the wind farm model. Determining a system deviation as a difference between the modeled active power setpoint value and an actual value of the active power output of the wind farm. Inputting the system deviation into a power controller which outputs a controller manipulated variable. Determining a feedforward controller manipulated variable independently of operating states of the wind turbines of the wind farm or the active power. Determining an overall manipulated variable as the sum of the freeforward controller manipulated variable (uff) and the controller manipulated variable.

摘要： A method is provided for operating a wind turbine having an elongated stand apparatus, a generator rotatably mounted on the stand apparatus, and a rotor coupled to the generator via a rotor hub and the wind turbine also having an elongated rotor blade. A position of a radar system is determined with respect to the wind turbine and at least one area is determined for the rotational axis of the rotor as a function of the determined position which is not intended to be permanently assumed for alignment of the rotational axis of the rotor about the longitudinal axis of the stand apparatus. The wind turbine is operated with the at least one determined area not being permanently assumed for the alignment of the rotational axis of the rotor about the longitudinal axis of the stand apparatus.
